FAN-MOUNTING.

Application :ned April 12, 1918. serial No. 228,098.

To all whom it may concern.'

Beit known, that I, CARI. Gr. Swanson, a citizen olt tbe United States, residing at Indiauapolis, in the county of Marion and State of indiana, have invented. a neu1 and useful. Fan-Mounting, of which the following is a specification.

In `the manufacture of automobile radiator fans, it is found that substantially the same fan is required for many different makes of automol'iiles; but that in attaching. these fans to automobiles of different makes a different distance mut be provided between the plane of attachment of the fan to the motorand the plane of the belt "wl'lich drives the tan.

Itis the object of my present invention to provide-a. construction whereby insuch a radiator this distance may be made anything desired Without requiring any change in the other parts of the fan, so that fans made of the same component parts ma be used for different types of automobiles, aying different distances between the plane of attachment and the plane of the driving belt. f

The accompanying drawing illustrates my invention. Figure 1 is an axial section throng-h a hub-drive fan and its support,

' lstud shaft.

With'the fan blades partly broken' away, showingV one embodiment of my invention, with a pulley attached to the outer menrber of the fan bearing by rivets; Fig. 2 is a somewhat corresponding View, but with the partsrmainl-yin elevation, 4and with the pul` leyattachedl tosaid outer member by spot Welding; Fig. 3 ie a View somewhat simil-.ir to Fig, l, but of: a spindle-drive fan; and Fig. 'l'is 'a section on the line 4-l of Fig. 3. In the arrangements' shown in Figs. 1 and 2, there is a, stationary stud shaft 10, mount ed on a. support 1l from the motor` as by passing through a boss 12 of such support 1l and being clamped to such boss between Va collar 13 on said stud shaft and a nut laf cooperating `with the threaded end l of said The plane of engagement i6 between the support 11 and the collar 13 determines the relativeposition of the stud shaft 10 with'relation to the support l1.

rEhe stud shaft l0 carries ball cones 20, adjustafble toward and from each other as by having one of them lmounted on the threaded outer end of the stud shaft l0; and bel tween these ball cones 20 and ball races 21 IANA?, AssrdNon (To 1 A coR/PonA'rIoN Y0F INDIANA.

The hub menilsii' 22 is provided atone end with an outturned. flange 25, to whic is fastened the' fan blade assembly 26.` Sa e for this outturnedlla'ngge 25, the hub member 22 is tubular in form', Mounted on this tubular hub member 22Y isit pulley 27 of any suitable structure. This pulley may be fastened to the hub member 22 by spot welding, as in Fig. 2, or by rivets 28, as in Fig. 1; such rivets 28 in the lutter case also preferably passim through thf spacing member 24 t0 position it with spect to the hub member. The pulley 2Tf1n'a be, slid toV any desired position along th f hub member 22 before bein 'fastened tl'ieijefi to byA the spot welding or t le rivets, hat the distance a between the plane 21)`of`=suc li In consequence, t e same fanfparts may`fbe used for any desired value offthe distancei'ta without requiring lany other change than the positioning oi the pulley 271ml the' hub' meiil itt ber"22- By this arrangement,'the same fain?, with all the same component parts, may be used for different types of motors, haring different requirements for'the distance A very similar structure lfor obtain similar results may also lit-used'for a spinu dlefdrive fun, as shown in l`igs. 3 and4. llore thev o'uter member 30, correspondinigbo the hub 22 in the arrangement shownl-in Figs. l and 2, is stationary:insteado, rota table, and the inner'member 31, oorres'ioml- 95, ing to the stud shaft l0 of Figs. l an 2, is. rotatable instead of stationary, these inner and outer parts being; relatively rotatable on ball bearings 23 mounted between hall cones 2() and ball races races being separated by a spacer 24, here made oi sheetmetal stampings. '.lheinner rol tat'able member 31 carries a pulley 32 at one end, and has a fan, attached thereto at the i `other end in any suitable manner, not shown. 1054 2l as before, and the ball 10 usual manner. The axial position of this socket 35 on its supportin r stud is determined by the plane. ot' engagement 3G be.- tween one axial end ot' such lsockelI and the l of said stud, and the distance a, between such plane 36 andthe plane IS7 ot' the pulley 32 varies in different automobiles. This distance may be varied with the. same fan parts by slidingr the .soiaet 33 and the .tubular member 30 axially with relation to each other, to obtain the desired distance a; and after this is done the parts 30 and 33, and convenientlyY also the part '24, are suit-ably fastened together by. rivets 38. By this arrangement, the same tan, comprising all the same component fan parts, may be, used for motors requiring" diterent values ol' the distance a.

I claim as my invention:

l. A fan mounting, comprising` an inner member, an outer tubular member. one ot said members being stationary and the other being mounted thereon tor rotation relatively thereto, a fan carried by said rotatable member7 a fixed support and a pulley with which said stationary and rotatable members a re respectively associated, that one of said parts which is associated with lthe outer tubular member having an initial slidable fit over said tubular member so that it ean be broughtto different axial positions thereon in assembling and being rigidly attached to said tubular member after being brought to the desired position so as to fix 4the variable axial distance between the plane of said pulley and the plane of said support.

2, A fan niountine` comprising` an inner member` an outer tubular member, one of said members beingr stat ionary` ball bearings by which the other of said members is mounted ou the fixed meml'ier, a fan carrie-d by .said rotatable member` a fixed supportl and a pulley with which said .stationary and rotatable members are respectively associated, that one of said parts which is associated with the outer tubular member having an initial slidablctit over said tubular tion so as to fix thevariable axial distance between the plane of said pulley1 and the plane of said support.

3. A fan mounting, comprisingr an inner member. an outer tubular member, one ot' said members being stationary and the other being mounted thereon for rotation relatively thereto, a fan carried by said rotatable member, a fixed support and a pulley with which said stationary and rotatable. members are respectively associated, that, one of said parts which is associated with the outer tubular member having an initial slidable tit over said tubular member so that it can be brought to different axial positions thereon in assembling, rivets attaching together .said tubular men'iber and the part associated therewith after they are assembled in proper position and thereby fixing the variable axial distance between the plane ot .said pulley and the plane of said support'.

,4. A fan mounting, mmprising an inner member, an outer tubular member` one of said members being' stationary, a pair ot spaced ball bearings between said two members` a spacer within Isaid tubular men-.ber for spacing apart the ball races of said two ball bearings, a fan carried by said rotatable member. a fixed support. and a pulley with which said stationary and rotatable menibers are respectively associated, that one of said parts which is associated with the outer tubular member havingr an initial slidable titJ over said tubular member so that it can be brought. to different axial )ositions thereon in assembling, rivets attaching said Spacer to said tubular lnei'nber and both to the part associated with said tubular member after they are assembled in proper position and thereby fixing the variable axial distance between the plane. of said pulley and the plane of said support.

In witness whereof, ,lf have hereunto set, my hand at Indianapolis, Indiana.` this tent-h day of April, A. D. one thousand nine hunn dred and eighteen.
